Before 2006, mainland China LED applicant for a patent for invention mainly is composed of national 863 plan projects such as unit and implementation. After 2006, LED the enterprise as the LED of the applicant for a patent for invention patent application number increase quickly. Along with the development of the market, the Chinese LED enterprises, technical strength and the patent protection consciousness has been improved remarkably, and gradually mastered by patent increasing wealth and methods to avoid risks.
According to relevant data shows, at present in the field of global LED technology and patent, more than half of the international big company. Japan, the chemistry, synthesis, the United States CREE, Toyota Europe philips, osram European and other foreign companies, the hands have a lot of patents, covering the raw materials, equipment, packaging and application, almost the entire industrial chain. An application for a patent for the LED industry in China, by contrast, mainly concentrated in the middle and lower reaches of industry, including application link in the middle encapsulation, patent accounted for over 60% of the total application, an application for a patent for utility model and the application for a patent for design is given priority to, an application for a patent for invention is low. Especially in relation to the industry for the long-term development of key technology link, still lack of the core patents. Clearly, foreign patent monopoly industry giant, seriously hindered the development of LED industry in China.
We make a survey in LED lighting market that more and more LED products like 5W LED Candle bulb, 100 watt equivalent led and b15 bulb are applying for patent. This shows china LED enterprise has more and more innovation.
Peking University intellectual property related experts point out that the Chinese LED enterprises need to adjust the strategy, can be used by purchasing the patent authorization, but will have its own brand; At the same time, more domestic enterprises to improve their strength, relying on the academy, institutions of higher learning, cultivate their own patent talented person, taking the path of independent innovation, break through the foreign patent barriers. Only pay attention to the research and development, with independent intellectual property rights, improve product quality, to make the LED industry in China to get rid of this embarrassing situation had been.
